摘要
以三氨基三羰基铬与对二甲氨基苯甲醛缩巴比妥酸为原料,合成了一种新型高灵敏度检测三聚氰胺的红外化学传感器分子——对二甲氨基苯甲醛缩巴比妥酸三羰基铬。通过元素分析、质谱、核磁共振及红外光谱对其结构进行了表征。红外吸收光谱研究表明,在乙醇溶剂中,当三聚氰胺的浓度高于1.0×10^(-7) mol/L时,金属羰基的红外吸收峰与三聚氰胺的浓度呈线性关系。利用该红外化学传感器分子可初步实现对三聚氰胺的微量检测,检测误差低于5%。
A novel infrared(IR)chemosensor molecule,dimethylamino benzaldehyde barbituric acid chromium tricarbonyl,was synthesized by using(NH_3)3Cr(CO)3and dimethylamino benzaldehyde barbituric acid.The structure of this product was analyzed by elemental analysis,mass spectrometry,nuclear magnetic resonance spectroscopy and IR spectrometry.The results of fourier transform infrared spectrum indicated that,in ethanol solvent,the infrared absorption peaks of the metal carbonyl had a linear relationship with the concentration of melamine,when the concentration of melamine was more than 1.0 × 10^(-7) mol/L.Using this principle,it can be used for trace detection of melamine,detection error was less than 5%.
